I agree, with my luck if I did that work myself, the gun would never fire again. So, how much would a trigger job like that cost? Will it void any warranty? I might be inclined to have the work done.DANO said:While I don't feel comfortable filing off metal from the internal parts, I would still like to reduce the over travel. I want to try to increase the size of the trigger stop protrusion inside the trigger guard behind the trigger. Does any one have a suggestion as to what the best material is to use to build up that area?
